Monitoring of both the amount and the quality of the water being produced on well-by-well basis is a key building block for implementation of an efficient production strategy for gas field developments as the capability of handling produced water is typically a limiting factor. This paper presents a novel measurement system for subsea applications based on microwave reflection measurements. The shallow sensitivity depth of the sensor makes it ideal for detection of miniscule amounts of liquid water as well as estimation of its salinity. Furthermore, the measurement system can be employed to directly measure the ratio of hydrate inhibitor to water enabling substantial cost savings through chemical injection optimization.
